To all whom it may concern:

Be it known that I, RAYMOND N. Erin- HART, a citizen of the UnitedStates, residing at Edgewood, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement in Condensers,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification.

The present invention relates broadly to condensers, and moreparticularly to condensers of the jet type, although certain features ofthe construction are equally adaptable to general condenser work withcondensers of other types.

In accordance with my invention, meansof improved character are providedfor permitting access to the water-injection nozzles and to thecondensate pump.

In the drawings, the figure of which represents more or lessdiagrammatically one form of condenser in vertical section, there isdisclosed a steam inlet 2, having a surrounding water box 3. Leadingfrom the water box is a series of injection or'spraying means 4:,arranged to discharge into the inlet chamber. A

This inlet chamber is preferably made in a separate piece from the body5 of the condenser and the water box 3 is formed integrally therewith,the latter being of larger diameter than the body of the condenser, sothat its bottom wall forms a surrounding overhang. This overhang isprovided at intervals with hand holes 6, each of which is closed by ahand hole plate or cover 7 secured by a crab 8, located within the waterbox. The hand holes are so spaced and located and are suflicient innumber to give access to all the injection or spraying means of theseries. This not only makes it unnecessary to remove the inlet chamberto obtain access to the water box and nozzles, but it permits all theseats for the cover plates 7 to be made at a single facing operationduring the manufacture of the condenser. In the preferred embodiment ofthe invention, there is provided a centrifugal pump 9, having the usualdischarge pipe 10. The pump casing section 11 is made separately fromthe body 12, so as to permit it to be readily removed to give access tothe pump. Heretofore, in this general tackle connection for effectingthe removal of such covers. To overcome this dilficulty, I provide asuitable lug or bracket 13 on the intermediate section 14- of thecondenser, in which there is journaled a pulley 15. A line or cable- 16can readily be run over this pulley and down to an eye bolt 17, on thepump cover 11. ried olf horizontally, or in fact, in almost anyconvenient direction, to a block-andtackle. The cover may therefore beeasily raised out of position, a comparatively slight pull on the line16 serving to produce the necessary outward movement of the cover. Afterthe cover has been removed, the same pulley can be used to advantage inthe removal of the pump shaft.

Access to the interior of the condenser may be gained through a suitableman hole 18, closed by the usual cover plate, and vapors may bewithdrawn from the condenser through a suitably arranged outlet 19.

The present application is a division of my copending application,Serial No.

This line can be car-' 259,946, filed October 28, 1918, which eventuatedin Patent No. 1,533,840 of April 14,

1925. The features herein shown with respect to my jet condenser areshown in my divisional application filed June 16, 1925, Serial N 0.37,456.

The advantages of the present invention arise from a condenserconstruction in which ready access to all of the parts is permitted.

I claim:

1. A condenser having a water pump casing section provided with aremovable cover portion, and a lifting connection on the condenser forthe removal of said cover portion, substantially as described.

2. A jet condenser having a water pump casing section provided with aremovable projecting cover portion, and a lifting connection on thecondenser for the removal of said cover portion, substantially asdescribed.

supported on a partially overhanging portion of the condenser above saidcasing for cooperation with a cable, substantially as described. I

5. In a condenser, a water pump casing section supporting the same andprovided with a removable cover portion, and a lifting connection on thecondenser for the removal of said cover portion, substantially asdescribed. I

In testimony whereof I have hereunto set my hand.

RAYMOND N. EHRHART.
